The Carmex Thread Turning Holder Screw Clamp (External) is a precision tool designed for left-hand external threading tasks, delivering stable support and repeatable results on metalwork parts.

Built to work with 16EL inserts and featuring an 80 mm overall length along with a 12x12 mm shank, this holder offers robust rigidity and versatile compatibility for reliable threading operations.

• Left-Hand External Thread Turning Holder: Optimized for left-handed threading, ensuring correct cutting direction and chip flow for exterior threads.
• 80 mm Overall Length: Provides adequate reach for longer workpieces while maintaining rigidity during cutting.
• 12x12 mm Shank Size: Standardized interface for secure mounting in compatible toolholding systems.
• 16EL Insert Compatibility: Specifically designed to accept 16EL external threading inserts for precise thread profiles.
• ER/EL Inserts Compatible: Supports multiple insert styles (ER and EL) to cover a range of threading needs.
• U-Type Insert Ready: Engineered to accommodate U-Type inserts for enhanced stability and accuracy.
• 1.5° Helix Angle: Promotes efficient chip evacuation and smoother cutting action for improved performance.
• Rugged Screw Clamp: Secure, reliable clamping keeps the insert fixed under load, preserving thread tolerance.

With its precise clamping and dedicated geometry, this Carmex holder helps you achieve consistent external thread forms, minimize runout, and improve surface finish on cylindrical parts. The 1.5° helix angle and U-Type insert compatibility deliver efficient chip management and stable cutting, reducing downtime from tool changes. The combination of 80 mm length and 12x12 mm shank provides a balanced mix of reach and rigidity for a wide range of workpieces, while the screw clamp design enables quick, repeatable insert changes to maintain tight tolerances across production runs.
